Abstract:

A one pot three-component coupling reaction of phenylacetylene, aldehyde, and amine derivatives in the presence of Cu(Ⅱ) Salen complex as an efficient heterogeneous catalyst under solvent-free conditions is reported. The catalyst displayed high activity and afforded the corresponding propargylamines in good to excellent yields. This method provides a wide range of substrate applicability. The catalyst was reused several times without significant loss of its catalytic activity.

Key words: Propargylamine, Salen, Copper, Coupling reaction, Solvent-free
